Study on relation between regulation of MBL level and pulmonary tuberculosis susceptibility / 国际检验医学杂志

ABSTRACT

Objective To study the relation between the regulation of mannose‐binding lectin (MBL) level and pulmonary tuber‐culosis(TB) susceptibility .Methods A total of 142 inpatients with pulmonary TB and 120 healthy controls were recruited to par‐ticipate in this case‐control study .Serum MBL level was detected ,meanwhile the restriction fragment length polymorphism (RFLP) was adopted to detect MBL2 gene polymorphism .Results The one‐way analysis of variance was adopted to analyze the MBL level in different genotype groups ,including the group YA/YA ,XA/YA ,XA/XA ,YA/YB ,XA/YB and YB/YB ,it was found that the MBL level had statistical differences among 3 groups and between any two groups(P1 000 ng/mL ,while which in 100% individuals(26/26) carrying geno‐type XA/XA or allele B was≤1 000 ng/mL .Conclusion The MBL level may be associated with the susceptibility to pulmonary TB .The YA/YA gene for determining high MBL level may be a protected gene .
